@KathleenLD tweets us the photo above around 10:30am:
“People waiting to leave Pentagon City, no clue which track to be on”
WMATA tweeted earlier around 9:50am:
“Yellow/Blue Line: Single tracking btwn Pentagon City and National Airport. Track problem at National Airport. Delays in both directions.”
And then around 10:35am:
“Blue/Yellow: No longer single tracking. Expect residual delays in both directions due to earlier track problem near National Airport.”
